Currently, no. We wanted to keep the line width the same for both portrait and landscape mode so the text flow will not change when the interface orientation is changed. Also, the empty space next to the text is used for tapping gestures. If you tap with 1 finger on the right (left) space, the cursor will advance by one character (when the keyboard is active) to the right (left). if you tap with 2 fingers, the cursor will advance by one word.
